THREAD-130ARD-GTJ'IDE-VIRE HOLDER.

To aZZ whom it may concern-p Be it known that I, FREDERICK S. CUL- VER,a citizen of the United States, residing at Taunton, in the county ofBristol and State of Massachusetts, have invented a new and usefulImprovement in Thread-Board- Guide-lVire Holders, of which the followingis a specification.

This invention pertains to certain new and useful improvements in threadboard guide wire holders, and the primary object thereof is to improveand simplifythe finger head construction and to provide new'and improvedmeans for positively holding the head either in operative or inoperativeposition, which means is of simple and efficient character, and whichallows the head to be easily moved from one position to the other.

Further, the invention resides in certain details of construction andcombination of parts, which. will be more fully set forth in the courseof the following specification- In the drawingsFigure 1 is a side eleva-'tion of the invention applied to a thread board rail, the latter beingshown in fragment and in section, the finger head being illustrated inoperative position. F ig. 2 is a similar view showing the head inraisedor inoperative position. Fig. 3 is a bottom plan view of the invention,in detached relation to the board, and Fig. 4; is a perspective view ofthe head, the guide wire being omitted.

In accordance with the present invention the head is preferably formedof a section of sheet. metal, bent to form a trough-like structurepossessed of a body 1, sides 2, a front end 3, and a rear wall 4:,thelatter extending beyond the free edges of the sides 2 and formed of acontinuation of the body. The front end 3 is provided with a concaveseat 5 in which the shank 6 of the wire thread guide 7 is received. Therear or inner end of the shank 6 is bent into a U-shaped portion 8, thelegs of which portion en age the inner faces of the sides 2 to therebyold the shank against lateral movement relative to the head in'whichregard the seat 5 also acts to further prevent lateral movement of thefront end portion of the shank 6 as is evident from Fig. 3 of thedrawings.

The tail of the holder is formed of a member 9 which is secured to theunder face of the thread board rail T and which has a pair of perforatedforwardly projecting cars 10, which latter receive the rear ends i913.Serial iv fvsgisc.

of thesides 2, of the head, said rear ends having apertures 11 thataline with the perforations of theears lO-soas of the sides 2 to receivea pintle or pin .12, which latter serves to pivotally connect the headto the tail. The tail is 'also'providedwith apair of. spaced dependingperforated lugs-13 which receive a straight spring member 14, thememberli having a driving-fitin the perforations of the lugs,

The front or free end of the member 14bears against the free edge of the wall 4.- atthe rear of the head,,soas to exert sufficient tension on saidwall in order to hold the headeither in the position depicted in Fig. 1 or that of Fig. 2,;the member1 1- bearing on the wall. io'nly suf-' ficientlyto effectively hold thehead in the positions shown, so as to allow the head to, 5

the I threa head.

From the above it will be apparent that the head can be easily stampedfrom a single piece of sheet metal which involves minimum expense andlabor. Further, the entire structure is simple, and involves a'minimumof parts, whichcan be easily and quickly replaced, if damaged orrendered by wear In addition since unfit for further service. the springand associated parts face downwardly, they are subjected to protectionagainst injury in an obvious manner.

Having thus described my invention, I

claim as new and desire to secure by'Letters Patent 1. In combinationwith the-thread board rail, a tail member secured to the under face Anut and screw 15 is employed to secure the U-shaped portion of guide inposition relative to thego thereof, a pair of spaced perforated ears ona the tail member from, a pair of spaced perforated depending lugsspring member engaged in the perforations projecting forwardly thereon.thetail member, a straight of said lugs, a head formed of sheet metalblank having a front end formed with. a

concave seat, sides, and a rearwall which latter projects beyond thesides and is engaged at its free edge by the front end of the springmember, said sides at their rear ends being perforated and received inthe space between theears, a pin passed through theperforations oftheears and head sides,

and a thread guide securedto the head and i 65 7 so as to be secured vhaving the shank thereof engaged in said seat and having a U-shaped rearportion which engages the confronting faces of the sides of the head. 7

2. In combination with a tail member for securement to the thread boardrail, a pair of perforated lugs depending from said tail member, astraight spring secured in the perforations of the lugs, a head pivotedto the tail member, an abutment on the rear and formed from a singlepiece of sheet metal shaped to provide sides, a front end formed with aseat, and an abutment at its rear end formed from a continuation of thebody of the metal, a thread guide carried by the head having a partthereof engaged in said seat, and a spring carried by the tail memberand engaged with said abutment.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
